Make the dressing by combining all the ingredients. Taste, and adjust the amount of oil, vinegar (if using) and apple juice to taste.
Toast the pistachios in a pan (without oil) for 4-5 minutes.
Finely slice the apples, along with the fennel and radishes (after removing tops, fronds and stalks, as appropriate).
Combine all the ingredients in a bowl and toss to combine, I would suggest using half the dressing to begin with, and then adding more to taste.
Arrange on your serving plate, and sprinkle with thyme. Enjoy!
Notes
Slice the apple, fennel and radish quite finely, particularly the fennel as it is quite fibrous. This will help it soak up the dressing also.
Use unsalted pistachios.
For a nut free option, swap out the pistachios for pumpkin seeds.
